That's an awesome change to Druid shrooms. Lay em out as much as you like to anticipate damage but only charged if you bloom them. Should alleviate much frustration from tanks dragging things off of where you thought they needed to be. At least you can move them now without going OoM

I wonder if the following change is a typo:
Blood Plague A disease dealing 107 172 Shadow damage every 3 sec for 30 sec.
Frost Fever A disease dealing 90 1,390 Frost damage every 3 sec for 30 sec.
Where changing frost fever from 90 to 1,390 is really supposed to be 139. It would be more on par with the blood plague change...

both dots do the same dmg on the beta , guess they made a mistake with blood plague in the notes

No, it was an accidental overbuff of Frost Fever:

Was an extra 0 mistakenly added to Frost Fever (should be 139)? Or is Blood Plague missing a 0 (should be 1720)?

The former. Frost Fever's base damage was accidentally increased too much. It should indeed be 139 at level 90.
